FIG. 1 is an exploded view of a charging box of an embodiment of the present disclosure. FIG. 2 is a section view of a charging box of an embodiment of the present disclosure along a plane A-A. As shown in FIG. 1 and FIG. 2 , the charging box includes a box body 1, a box cover 2, a battery 3, a charging assembly 4 and a circuit assembly 7. The box body 1 is internally provided with a product cabin 11 for accommodating a product, the box cover 2 is openably and closably arranged at an opening of the box body 1, and the battery 3 is arranged in the box body 1.

The charging assembly 4 includes a magnet pendulum bob 41 and a coil structure 42 arranged in a periphery of the magnet pendulum bob 41, where a first end 411 of the magnet pendulum bob 41 is rotatably connected with the box body 1 and a second end 412 of the magnet pendulum bob is a free end. As an electromagnetism induction phenomenon is a phenomenon that a conductor in a closed circuit performs a magnetic induction line cutting motion to generate an induced current in the conductor, i.e., in a using process, as the magnet pendulum bob 41 has a magnetic field around, under a condition that the conductor coil structure 42 is arranged around the magnet pendulum bob, a relative motion generated between the magnet pendulum bob 41 and the coil structure 42 will enable the coil structure 42 to cut the magnetic field of the magnet pendulum bob 41, so as to generate the induced current in the coil structure 42. In the embodiment, the coil structure 42 includes a coil bracket 421 that supports its structure, and the coil bracket 421 is made from an insulating material, so as to shield influence of an external magnetic field to the charging assembly 4.

A bottom of the box body 1 is formed as a curved surface, and is provided with a balancing weight 6. In the embodiment, the bottom of the box body 1 is formed hemispherical, and the balancing weight 6 is arranged at a vertex of a hemisphere. That is, the charging box is placed on a plane such as a desktop, the balancing weight 6 is capable of stabilizing the center of gravity of the charging box to the bottom of the box body 1, so that the charging box has strong stability. When the charging box is subjected to a certain external thrust to incline towards one side, the center of gravity thereof deviates therewith. At the moment, with respect of nature of the force, resistance will be generated between the charging box and the desktop to resist interference of the resistance, such that the charging box inclines towards the other side under the action of the resistance to perform a swinging motion for a period of time, so as to restore balance of the box body 1. For simplicity of description, the charging box may be regarded as a structure similar to a tumbler. In a using process, a user may apply a force to the charging box, so that the charging box produces a swinging motion, and therefore, the magnet pendulum bob 41 inside rotates as a result of inertia, so that the coil structure 42 may cut the magnetic field of the magnet pendulum bob 41 to generate an induced current.

Such a design may enable the charging box to be charged as the user pushes the box body 1, so that endurance of the charging box is increased. Moreover, the design similar to the tumbler may further enhance interestingness of the shape of the charging box, so that it is better in availability. Optionally, the bottom of the box body 1 may further be formed as other curved surfaces to realize similar stressed structures.

Further, a radial dimension of the first end 411 of the magnet pendulum bob 41 is smaller than that of the second end 412. In the embodiment, the dimension of the magnet pendulum bob 41 is gradually increased in a direction from the first end 411 to the second end 412, and a contour thereof is formed as a smooth curve approximating a drop shape. As the magnetic field intensity of the magnet is in direct proportion to the dimension of the magnet, and at the same time, the induced current generated by the conductor that cuts the magnetic field is also in direct proportion to the magnetic field intensity, the dimension of the second end 412 may be larger than that of the first end 411, so that the magnet pendulum bob 41 may provide a stronger magnetic field. Furthermore, as the inertia of an object is in direct proportion to the mass of the object, the center of gravity of the magnet pendulum bob 41 may be located at the second end 412, so that the magnet pendulum bob 41 may have a larger rotating amplitude. Optionally, the magnet pendulum bob 41 may further have other shapes. Besides, the magnet pendulum bob 41 may further have a mode of motion except rotation. For example, multi-angle rotating motion through a spherical hinge may also realize a similar effect.

However, as the induced current generated by the coil structure 42 that cuts the magnetic field of the magnet pendulum bob 41 is an alternating current and may not charge the battery 3 directly, the charging box is provided with the circuit assembly 7 electrically connected with the coil structure 42, so as to receive the induced current generated by the magnet pendulum bob 41. The circuit assembly 7 converts the received induced current into suitable currents capable of being electrically connected therewith to charge the battery 3 by other processing such as AC-DC or boosting.

FIG. 3 is a schematic structure diagram of a transmission part of a charging box of an embodiment of the present disclosure. As shown in FIG. 3 , the charging assembly 4 further includes a generator 43, configured to convert kinetic energy generated by motion of the magnet pendulum bob 41 into electric energy. That is, when the magnet pendulum bob 41 rotates as the charging box swings under the action of an external force, a torque generated by rotation of the magnet pendulum bob 41 is conducted to a motor shaft 431 of the generator 43, so that the motor shaft 431 rotates so as to further convert kinetic energy of the magnet pendulum bob 41 into electric energy. Furthermore, the generator 43 is arranged outside the coil bracket 421, so as to prevent a magnetic force generated when the generator 43 generates electricity from affecting the magnet pendulum bob 41 and the coil structure 42.

Therefore, the charging box further includes a transmission part 5, configured to transmit a motion of the magnet pendulum bob 41 to the generator 43. In the embodiment, the transmission part 5 includes a first gear set 51, a transmission bar 52 and a second gear set 53, the first gear set 51 being connected with the first end 411 of the magnet pendulum bob 41, the second gear set 53 being connected with the motor shaft 431, and the first gear set 51 and the second gear set 53 being transmitted by the transmission bar 52. The first gear set 51 includes a fan-shaped gear 511, the first end 411 of the magnet pendulum bob 41 being fixed to a center of the fan-shaped gear 511. That is, the fan-shaped gear 511 plays a role of amplifying a rotating torque of the first end 411 of the magnet pendulum bob 41. When the magnet pendulum bob 41 rotates, the fan-shaped gear 511 will rotate along with the first end 411 so as to drive the first gear set 51, and transfer the torque to the second gear set 53 through the transmission bar 52, so that the motor shaft 431 rotates eventually. Optionally, the transmission part 5 may further have other setting modes.

It is to be noted that as rotation of the magnet pendulum bob 41 in the embodiment is a motion of swing between +90 degrees and −90 degrees, the motor shaft 431 also reciprocates rotatably clockwise and anticlockwise therewith. However, the rotating direction of the motor shaft 431 does not affect power generation efficiency of the generator 43 because the generator 43 rotates in the magnetic field with a stator to convert kinetic energy into electric energy by way of cutting the magnetic induction line to generate the current. However, the current generated by the generator 43 is also an alternating current which may not charge the battery 3 directly. Therefore, the generator 43 is further electrically connected with the circuit assembly 7, so that the circuit assembly 7 may receive the current generated by the generator 43 and perform other processing such as AC-DC or boosting, so as to charge the battery 3.

Further, the charging box further includes a partition plate 12 arranged in the box body 1 to divide the box body 1 into a first cavity 101 and a second cavity 102. In the embodiment, a side of the partition plate 12 facing a curved surface at the bottom of the box body 1 is the first cavity 101 and the other side thereof is the second cavity 102. That is, the box body 1 is formed such that one side of the hemisphere is the first cavity 101 internally provided with the magnet pendulum bob 41, the coil structure 42, the generator 43, the transmission part 5 and the balancing weight 6, and the battery 3, the product cabin 11 and the circuit assembly 7 are arranged in the second cavity 102.

In the embodiment, the first end 411 of the magnet pendulum bob is rotatably connected with the partition plate 12. The connection is realized by a bolt, namely, a protrusion extends on the partition plate 12, so that the bolt passes therethrough, and the first end 411 of the magnet pendulum bob is further provided with a through hole where the bolt passes through. Optionally, the magnet pendulum bob may be rotatably connected with the partition plate 12 in other ways.

In the embodiment, the box cover 2 is rotatably arranged at the opening of the box body 1, so as to obtain an openable and closable effect. Optionally, an edge between the box cover 2 and the box body 1 may be provided with a magnet unit, so that the box cover 2 generates a magnet suction effect with the box body 1 when being closed, thereby improving the availability of the charging box. In the embodiment, the product cabin 11 is formed as a copying cabin of an earphone, so that an earphone product is partially exposed out of the box body 1 when the box cover 2 is opened. Optionally, the product cabin 11 may also be copying cabins of other products.

In the embodiment, the circuit assembly 7 may realize an effect of converting two alternating currents: the induced current generated by the coil structure 42 that cuts the magnetic field of the magnet pendulum bob 41 and the current generated by the generator 43 that converts kinetic energy of the magnet pendulum bob 41 into electric energy into direct currents and boosting the currents so as to charge the battery 3. Optionally, the circuit assembly 7 may further have other functions. For example, when electric energy in the battery 3 is saturated, the circuit assembly disconnects accesses between the circuit assembly and the coil structure 42 and between the circuit assembly and the generator 43, which is not limited herein.

A charging box provided by the embodiment of the present disclosure discloses includes a box body, a box cover, a battery, a charging assembly and a circuit assembly. The box body is internally provided with a product cabin for accommodating a product; the box cover is openably and closably arranged at an opening of the box body; the battery is arranged in the box body; the charging assembly comprises a magnet pendulum bob and a coil structure arranged in a periphery of the magnet pendulum bob, where a first end of the magnet pendulum bob is rotatably connected with the box body and a second end of the magnet pendulum bob is a free end; and the circuit assembly is electrically connected with the coil structure and the battery, where a bottom of the box body is formed as a curved surface. The charging box further includes a balancing weight arranged at the bottom of the box body. Therefore, according to a technical solution of the embodiment of the present disclosure, by arranging the charging box in a special shape, the charging box is in form of a tumbler, so that in swinging process of the charging box, the coil structure may cut a magnetic field of the magnet pendulum bob to generate induced current to charge the charging box so as to increase endurance.
